Might be QNX, I know quite a few commercial radar systems (mostly ones privatly owned for weather stations) that run on QNX.
It might also be a completely proprietary system, or an oldschool WANG VS or IBM mainframe, or even a basic UNIX mainframe.
From just a screenshot of the output you can't really find out.
Knowing what radar system it is, what model and what manifacturer, it would be easyer to find out.
